Special Issue Information

Dear Colleagues,

Fruit tree diseases and pests have a great influence on agricultural production worldwide and a global economic impact through the loss of productivity and trade limitations. In recent years, due to global warming and environmental changes, yield loss and fruit diseases are occurring more frequently than ever. The production of disease-free fruits and minimizing the diverse effects of biotic stresses is crucial to increase the food supply for a continuously growing human population and strengthen the worldwide global economy. Accurate diagnosis and early detection of plant pathogens and pests help to identify appropriate management practices to reduce production losses, decrease disease spread and increase the chance of effective eradication when new pathogens are introduced into a country. Research on all topics related to fruit diseases, such as fungal, bacterial, viral, nematodes, etc., and pests, from the development of novel, rapid, specific and sensitive fruit disease/pest detection/diagnostic methods to developing basic and applied control and management approaches, is a priority.

This Special Issue will focus on the “Detection and Control of Diseases and Pests in Fruits”. We are open to novel research, reviews and opinion articles covering all aspects of the detection and diagnostics, surveillance and/or forecasting of transboundary, emerging, re-emerging and invasive pests and diseases associated with fruit trees, a rapid response to, and recovery from pests and diseases that pose threats to fruit production and the food supply system, as well as those that suggest management practices and innovative strategies that can control or minimize the impacts of pre-harvest and post-harvest invasive, emerging and re-emerging diseases and pests in fruits.

We evaluated the effectiveness of three different treatment groups at managing apple shoot blight, and the resulting canker incidence and canker length on wood caused by Erwinia amylovora. Preventative foliar sprays or trunk injections of giant knotweed extract (Regalia), oxytetracycline (Arbor-OTC or FireLine + Regulaid), or streptomycin (Agri-mycin/FireWall + Regulaid) were applied to mature ‘Fuji’ trees. Regalia and oxytetracycline were ineffective at reducing shoot blight severity, showing poor disease reductions of 18.2% and 24.3% compared to untreated controls across both years. Streptomycin was effective at controlling shoot blight severity when applied as a spray application, reducing necrosis by up to 93.9% across both years. Canker incidence was also poorly reduced by Regalia and oxytetracycline with an average decrease of 33.3% and 52.4%, respectively. Again, spray applications of streptomycin were most effective at reducing canker incidence (95.2%). When present, canker length was best controlled by spray applications of streptomycin, showing an average reduction of 95.7%. The effectiveness of Regalia and oxytetracycline was poor, reducing canker length by only 30.4% and 43.5%, respectively. Trunk injections of Regalia were consistently less effective than spray applications. Compared to their spray application counterpart, Regalia injections were, on average, 12.5%, 26.3%, and 25.1% less effective at reducing shoot blight severity, canker incidence, and canker length, respectively. Injected Arbor-OTC was more effective than spray applications of oxytetracycline. On average, Arbor-OTC injections were up to 28.3%, 40.1%, and 30% more effective at reducing shoot blight severity, canker incidence, and canker length compared to spray applications. Overall, Regalia and oxytetracycline were not as effective as streptomycin at controlling fire blight. The search for organic antibiotic alternatives for shoot blight and canker control continues, as cankers are increasing in economic importance by causing bearing wood and young tree death.
